Thanks for the chip info

This really is an "ask and you shall receive" place. Thanks very much Synthex for the response.
The invensense 6050 includes the accelerometers, which was what I was most interested in. It also has some powerful DSP and firmware in it.
I wonder how the v929 flies so well with no accelerometers for level sensing.
Also, thanks for bonus datasheets.

I would echo neobot's comments about how this is very useful info, and I would also like to see it in reviews, but would caution that there is much more than hardware in this sort of product. The V929 has some very smart software in it to do what it does. Its "synthetic autolevel" appears to do a better job than the KK2 with leveling accelerometers. I hope there will be auto flipping built into the KK2 and arduino code. I suppose there will be a hundred more parameters needing tweaking if there is

I'd like to thank Synthex's posting specs and Islero is right, ask you shall recieve. I've taken transmitters apart before to show chipsets but most inquiries about details were for modding or hacking.

Interesting, do you have the programming knowledge\equipment to do so?

I have programming knowledge on Microchip PIC and Atmega, but not yet on ARM ...

This Serial Wire Debug port (SWD) can :
■Run Control of the processor allowing you to start and stop programs
■Single Step one source or assembler line
■Set breakpoints while the processor is running
■Read/write memory contents and peripheral registers on-the-fly
■Program internal and external FLASH memory

Cortex-M processor-based devices use the ARM CoreSight™ technology which introduces powerful new debug and trace capabilities.

Great job S,
It is interesting that the manufacturing date is only about a month different between the two revisions. On the Rev 6 V202 flight controller, did they fix the hover glitch on the left front arm motor and the need to set the trims back pitch 8-10 clicks and right aileron 6-8 clicks?

We use an SWD and USB TTL and the STM Flash Loader with the AutoQuad, UAVX32Arm32F4, Naze32, which all use 32 bit Arm processors. It would be fun to modify some open source code for these micros

The Revision 6 board still has the veer-off to the left and trim issues, but it does fly a little better. I can't exactly pinpoint what it is........maybe a bit more aggressive? There is also 2 revisions of the remote, Rev 1 and 2. I have yet to determine a difference between them (and it's not Mode1/2).

Lucky it was light fresh snowfall, or else I wouldn't of even seen the entry hole.

Such KK2 sacrilege!!! "self level in fw 1.4 is very good" and works very like the V202 (so how is it inferior ) and an "autoflipping KK2" ???? I'll sell all my KK2s if that ever happens. Learn to flip a Ladybird or something 1st.... it's NOT hard. (2 days ago, was just flipping my KK2 quad on low rates.... small loops instead of flips! ) freaked me out doing the 1st low-level flip. lol

Hi S,
Yes! Look for the ARM F3 and F4 Discovery boards. They have an onboard SWD. Sometimes they give those away at trade shows, but Mouser and Digikey also have them for around $20.

The Mini Pet is a beginner's or leisurely-flying quad. It hovers extremly stable and is a gentle flyer. Of course I'm sure it would perform better in advanced mode, but it's too prone to accidentally flipping in advanced mode. It has the typical hum of other quads which the V202 has eliminated (with use of a coil I'm assuming).

The V202 is a high-end sports car. The main drawback is the slower yaw rate. Minor quirks are hands-off hover and the occasional veer to forward left, but with Mini Pet props these minor quirks almost go away. It's nearly bulletproof. The Mini Pet is tough too but does have a weak spot being the battery tray.

Both are good night flyers with the MP having slightly better lighting. The V202's prop color scheme (if you keep using the stock props over the Mini Pets) has the best visibility, which the Mini Pet used to be able to lay claim to.

Flips are effortless on the V202. On the Mini Pet you can use a button or do manual flips like the V02, but you have to be in advanced mode, where it's too easy to accidentally flip and crash.............the V202 when you do an accidental flip, it always follows through........no crashes.

In a nutshell if you've never flown anything before, I'd suggest the Mini Pet, although you could also learn on the V202 if you're the type that gets right back on a horse you've fallen off of. If you've flown before get the V202.
